动物体型越大，其体表体积比越低；躯体每增加一盎司的重量，所能散发热量的表面就成比例减少。
The bigger the animal is, the lower its surface-to-volume ratio; for every ounce of body mass, there is proportionately less surface through which heat can escape.
这意味着释放等量电力的情况下，需要的硅晶体更少，但这也使得硅更热——与商业微处理器差不多的发热量。
That means you need less silicon to make a given amount of electricity, but it also makes the silicon very hot-as hot as a commercial microprocessor.
专利中描述了实现这种技术的几种方案，其中一种方案使用红外光电探测器来测量人体的体温，心率以及发热量等数据。
In one of the examples provided in, an earbud could include infrared photodetectors that would measure the user's body temperature, heat flux and heart rate.
